MACHINE FOR FORMING PILE ON WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 246,005, dated August23, 1881 Application filed March 21, 1881.

To all whom it may concern:

Be it known that I, GEORGE W. GRIFFIN, of Franklin Falls, coun ty ofMerrimack, State of New Hampshire, have invented an Improve- 5 ment inMachines for Forming Pile on Woven Fabrics, of which the followingdescription, in connection with the accompanying drawings, is aspecification.

' This invention relates to a machine for forming a pile on a wovenfabric, and is chiefly designed for manufacturing rugs, &c., from rags'or thrums or any usual carpet-yarns.

In the class of rug or carpet to be made by my mechanism or apparatusthe foundation is I usually composed of a woven fabric of jute or hempof coarse texture, printed or stamped on one side, in accordance withthe design or outline of the figure to be wrought upon the foundation ofthe pile. In accordance with my invention this fabric is laid upon thesupport ing-table, and is moved or fed along thereon in the properdirection to place the stamped or printed lines correctly above theperforatin g-needle and pile-inserting instrument when 2 5 the former isforced upward through the fabric, making a hole for the passage of thepileinserting instrument, it forming a pile-loop in and above thefabric, after which the needle and then the pile-inserting instrumentwill be withdrawn, leaving a pile-loop to be subsequently out, ifdesired.

Figure 1 represents, in front elevation, mechanism embodyingmyinvention; Fig.2, arighthand-side elevation of Fig. 1, the lowerframework being broken away; Fig.3,a partial section on the line a; 00,Fig. 1; Fig. 3*, a partial left-hand-side elevation of Fig. 1. Figs. 4,5, 6 are details representing the perforating-needie and pile-insertinginstrument in different positions.

In the drawings,Arepresents a supportingplate for the fabric a, (seeFigs. 4 to 6,) in which the pile b is to be inserted in the form ofloops, the said pile being composed of what is known as carpet-rags, orthrums/ or carpet-yarn. This supporting-plate A, sustained by asuitableframework, B,is provided with a throat, c through which theperforating-needle 0 and the pile-inserting instrument (No model.)

(I may pass to enter the fabric a. The perfo- 5o rating-needle 0, madeas a small tube of steel, and having at one side an eye, 0 for the reception of the pile material b,is secured to a block,

0, fitted loosely in a hole made in the end of the lever 0 pivoted at con the depending bracket B extended downward from the supporting-plateA, the said lever having a pin or stud, 0 which is acted upon by the cam0 (See Fig. 3 and dotted lines, Fig. 3.) The lever 0 which carries theneedle, has connected with it an adjustingplate, 0, provided with aslot, 2, through which is extended a set-screw,

e, the said set-screw being screwed into the lever c and holding theplate 0 in adjusted position. This needle 0 penetrates the fabric a,making a hole for the reception of the pileloop b, and also serves,during such operation, to feed thefabrie forward the length of thestitch or the distance required between adjacent loops of pile.

It will be obvious that the extent to which the fabric a will be movedas it is being penetrated by the needle 0 will depend upon the angularposition of the needle with relation to the lever 0 for the more theneedle is held toward the left, Fig. 3, or the more obtuse the angleformed by a line parallel with the axis of the needle with a line drawnfrom the center of the block 0 to the center of the pivot 0 the greaterthe feedstroke, so that by adj ust- 8o ing the position of the needle 0with relation to the lever c by the screw 6 the length ofthe feed mayreadily be regulated. A spring, 6 Figs. l and 3, connected with an arm,6 of the block draws it toward the pin 6 con- 8 5 nected with theadjusting device 0, but permits the said arm 0 to recede from the pin0*, as shown in Fig. 6, when the needle is withdrawn from the fabric, sothat the said needle passes out therefrom without moving it backward, as0 shown in Figs. 5 and 6,at'ter which the spring 0 brings the arm 0again in contact with the said pin a changing the angle of the needle sothat it enters the fabric at a point forward of that at which it leftit, as shown in Fig. 4, 5 and as the said needle passes through ininserting the pile it feeds the fabric forward, owing to the fact thatwhen in its normal position with the arm 0 against the pin c the pointof the needle is farther than its shank from its center of movement 0The pile material I) inserted in the eye of the needle, and along outthrough the needle, is passed over the end of the pile-inserting deviced, and while the needle is rising, as in Fig. 4, and is penetrating thefabric, as in Fig. 5, the pile-inserting device also moves'upward toproject the. material for the pile up through the hole made in thefabric by the needle, and while the needle 0 is drawn down by the cam cthe pile-inserting device retains the pile, as in Fig. 6; but after theneedle arrives below the fabric the pile-inserting device is drawn downand the needle is thrown back into the position, Fig. 4, ready to beagain elevated or projected through the fabric.

The pile-inserting device is connected with the lever 01, pivoted at (1and havinga pin or Stud, (1 which is entered within the cam d suitablyshaped to impart to the said lever d and pile-inserting device movementsin the order specified.

The two cams referred to are placed at opposite sides of the end of thelever E, having its fulcrum at 4, the lower end of the said lever beingmoved by the foot or pedal in any usual way.

In the drawings, Fig. 2, the cam 61* is supposed to be moving in thedirection ofthe arrow f, the center part, f descending to the right ofthe stud (1 but as the cam reaches its lowest position the said studwill he' forced past or across the top of the part f so that as the camd is elevated the centerpart, f passes to the left of the said stud, thelatter being caused to travel down between it and the switchcam 9, heldup by the spring h, the switch turning down for the passage of the studbelow it, and as soon as the stud passes the point of the switch-cam thelatter is quickly thrownv upward by the spring, so far closing the spacebetween its point and the piece f as to prevent the stud 61 from passingupward between them.

1 do not desire to limit my invention to the exact construction ofdevices for moving the needle and pile-inserting instrument.

I claim- 1. The open-ended hollowor tubular needle 0 with an eye at oneside, combined with the pile-inserting instrument located within thesaid needle, and with means to move the neodle to perforate the fabric,and then move the inserting-instrument through the hole made in thefabric by the needle, substantially as described.

2. The needle-carrying lever and needle pivoted thereon, and thepile-inserting device, combined with the adj ustin g-plate, adapted tobe fixed on the said lever to control the position of the needle, andthe spring 0 whereby the said needle and pile-inserting device arecaused to enter and leave the fabric at different angles thereto, forthe purpose of feeding it, substantially as described.

In testimony whereof I have signed my name I to this specification inthe presence of two subscribing witnesses.

GEORGE WV. GRIFFIN.
